FStaticMeshLODResourcesToDynamicMeshcan be used to create aFDynamicMesh3from aFStaticMeshLODResources, which is the variant of the mesh in a StaticMesh Asset used for rendering (and which is available at runtime). TheFStaticMeshLODResourceshas vertices duplicated at any split UV/normal/tangent/color, ie in the overlays there will be a unique overlay element for each base mesh vertex.
